The automatic windows on my 2005 Volvo XC90 roll back down after they have closed.

Does the computer think that something is stuck in the window, and roll it down?

It doesn't roll both of the windows at the same time.

Sounds like it might, but both windows? More than likely has something to do with the Body Control Module - BCM (or whatever volvo calls it). I'm not too knowledgable about Volvo's so hopefully someone else can give you more accurate information. –  Paulster2 Jul 8 at 17:25
    
Many vehicles equipped with remote keys have a "hidden" feature in which the windows roll down when the unlock button is pressed for a few seconds. It may be that the unlock button is stuck and causes your windows to roll down. If this is the case, the windows should not roll down if you use a different, working remote or the existing remote is far away from the vehicle. –  Zaid Jul 9 at 7:38

The cheapest, easiest thing you can try is to disconnect your battery for 30 minutes (check your owner's manual for the proper way of doing this). When you connect the battery again, your electric windows would have reset their soft limits (so called because the SOFTware learns what "fully open" and "fully closed" "feels" like). You'll notice that your windows won't automatically open or close all the way when you press the button, you'll have to hold it in until they go all the way up or down. You'll need to do this a few times until the software "learns" where the limits are. After that, it should be fine. If not, at least you haven't spent any money yet.

The next step would be to go to an auto-electrician.

Can You open windows with remote key ? Some models have feature, that pressing unlock button for about 5 or 10 seconds vehicle unlocks and all windows goes down. If windows is opened, then press and hold lock button for about 5 or 10 seconds and then windows must close. In that way you can check if its mechanical (switch) problem or electrical (computer) problem. If you does not have that feature, then it is harder to detect problem. Probably must connect to VIDA/DICE tool and read according electronic device errors. And witch window that is ? Driver doors or another? Does that happens with driver switch or with according door switch too ?
